Enumerate() in Python
Often, when dealing with iterators, we also get a need to keep a count of iterations. Python eases the programmers’ task by providing a built-in function enumerate() for this task.
Enumerate() method adds a counter to an iterable and returns it in a form of enumerating object. This enumerated object can then be used directly for loops or converted into a list of tuples using the list() method.
enumerate(iterable, start=0) Parameters: Iterable: any object that supports iteration Start: the index value from which the counter is to be started, by default it is 0
Return type: < type 'enumerate' > [(0, 'eat'), (1, 'sleep'), (2, 'repeat')] [(2, 'g'), (3, 'e'), (4, 'e'), (5, 'k')]
Using Enumerate object in loops:
(0, 'eat') (1, 'sleep') (2, 'repeat') 100 eat 101 sleep 102 repeat 0 eat 1 sleep 2 repeat
